We consider that the EditRecurrenceDialog should not be visible when double clicking or choose 'Edit Appointment' option from context menu of single occurrence. All fields for editing the occurrence are available in the EditAppointmentDialog. The same behavior is observed with Microsoft Outlook Calendar too.
If you still need to show the EditRecurrenceDialog on double click, you can use the suggested workaround in the issue`s description. Alternatively, you can subscribe to the AppointmentEditDialogShowing event and show it. Please refer to the code snippet below how to achieve it:
bool flag = false;
void radScheduler1_AppointmentEditDialogShowing(object sender, Telerik.WinControls.UI.AppointmentEditDialogShowingEventArgs e)
{
if (flag)
{
return;
}
else
{
e.Cancel = true;
flag = true;
radScheduler1.ShowAppointmentEditDialog(e.Appointment, e.Appointment.MasterEvent != null);
flag = false;
}
}
